 hi mike, hi steve, i did not receive a response on the queries about
the additional recommended options [1], so rather than lose track i
raised a bugreport and cross-referenced this discussion:

 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=919882

 personally, after using the ld-evil-linker.py tool i do not expect
the recommended options to work on 32-bit, as i suspect that, despite
the options saying that they do not use mmap, the investigation that i
did provides some empirical evidence to the contrary, whereas ld-bfd
does *not*.

 so, ironically, on ld-bfd you run into one bug, and on ld-gold you
run into another :)
